The Caratacus Stone, sometimes known as the Caractacus Stone, is an inscribed stone on Exmoor in Somerset, England. It is thought to date from the 6th century, and it has been a scheduled monument since 1925.The inscription, in Latin, appears to read CARAACI NEPVS, though experts have stated that a bar above the second A forms a ligature meaning that it should be read as CARATACI NEPVS.
